RETAINING-VALVE BRACKET.

Application filed September 8, 1925. Serial No. 55,011.

The retaining valve is part of the air brake system and functions toretaina certain part of the brake cylinder pressure to aid 1n retardingthe acceleration of a tram 1n descending long grades while the brakepipe 1111, Figure 10.

pressure is increased after one application to recharge the auxiliaryreservoirs.

This valve is usually bolted directly to the end wall of a car with theheads of thebolt on the inside of the car. It is not an unusual thingfor the air pipe to break where it enters the valve, in which event thevalve must be removed fromthe car, and if the carhappens to be loadedthe load must be removed from one end of the car to remove the bolts orto keep them from turning when the nuts are backed off the bolts. Underthe present system, when a pipe breaks itis necessary to place a newpipe from the union under the car to the valve, or place the bolts loweron the car wall necessitating the making of new holes in the car walland plugging the old holes, which, of course, is objectionable.

One otthe objects of my invention is to" provide a bracket for theretainer valve which can be readily and permanently secured to the carwall to which the valve may be detachably secured and provide meanswhereby the valvemay be secured in various 7 adjusted positions ascircumstances may dee mand, all of'which is accomplished wlthoutentering the car.

air pipe to the-upper end'of which cured the retaining. valve 14;, g 1Referring to Figures 1 to l," of the drawng, my retaining valve orbracket comprises a center plate 15 provided with, laterally extendingarms 16 at its end which are secured to the plate 15 by meansjof spacingmemis sehers 17 the arms 1.6 having suitable bolt or rivet openings 18through whichbolts or rlvets pass to secure the anchor, or bracket, tothe car wall permanently andwhen so secured the plate 15'is spaced fromthe car V wall in which space the heads 19 of the bolts 20 arepositioned.

The plate 15 is provided with rectangular openings 21 through which thehead 19 of the bolt may pass and from one side of this opening 21extends a slot'22 which opens into a vertical elongated slot 23, wherebythe bolt 20 may be slipped from the opening .21 through the slot 22 and.into the elongated slot 23, the elongated slot .bein the head ofthebolt.

. After the bolts 20 are in the slots 23 the bolt openings usuallyprovided in the lugs 24 are aligned with the bolts 20 and pushed towardthe bracket after which the nuts25' are screwed on the bolts 20until thevalveis firmly bolted on the plate15.

g smaller than 20 are positioned in the upper end of the elongated slot23 so that that .may be placed 0 in a. lower position in said slot toaccommo date a shortening of thepipe 13 without disturbing the positionof the'anchor on the car. v It will be readily seen that by simplyremoving the nuts 25 the valve maybere' moved from the bracket oranchor.

The only difference in construction in. Figures 6 to 9 from that shownin Figures that is common to both'slots 22*,tlie' elour gated slots 23"?being the same.) I also proa 1 to 5 is that I provide a bolt opening 25.3

thereby increasing the bearing of the bracket on the car wall.

In Figures 10 to 12 the anchor comprises,

a hanger plate 29 -having bolt openings30 therethrough to re'ceivebolt'stosecure' it to the car. ,At the lower end of this plate 29 is aforwardly extending shelf 31 from the outer edge of which depends anapron 32, there being ribs 33 extending fromthef fili 7 lower edge ofthe plate to the lower edge of the apron. iih 34 also extends betweenthe shelf 31*an'd the plate 29.

:As will be seen in Figure 10 there is an enlarged'space 35 open at thebottom and a common to the slots 23 to facilitate the movement of thebolts 20 toward. the slots maybemoved'towafd'the ends of the anchor.through slots into the elongated slots and that in each instance thehead of the bolt is Wider than the-elongated'slots that there is nodanger of the heads pulling out through said elongated slots.

What I claim is: i z' A bracket for a retaining valve including a plate,elongated vertically disposed slots near the ends of said plate, a slotextending; sidewise "from the elongated slots, and a bolt head openingin communication With said sidewi'seextending slots.
